Based on the variables available in the datafile, develop 2 research hypotheses that can be tested using a correlation test, chi-square test, or t-test. (note: you may not simply repeat the tests that you ran for Data Analysis Assignment: Part 1).

You also need to report the descriptive statistics (mean and standard deviation OR frequency and percent; decide which to present based on the level of measurement for the variable) for the following variables:

age

sex

 CorrelationsOnline Correlation CalculatorYou can run correlations using the Pearson Correlation Coefficient Calculator (http://www.socscistatistics.com/tests/pearson/Default2.aspx (Links to an external site.)Links to an external site. Links to an external site.). If you use this option, you will to also use a second calculator (link provided on the first page) to determine whether the results are statistically significant.Here’s the link to the video I created that explains how to use this calculator:https://youtu.be/sen9mJIEFtQLinks to an external site.Transcript of videoActionsHow to Write Up Your ResultsYou want the significance (2-tailed) number to be .05 or less.If the results are statistically significant, I would write up the results as: “There is a significant correlation between ** and **, r = **, p < .05.” (replace the “*” with information from your study output)If the results are NOT significant, I would say, “There is not a significant correlation between ** and **, r = **, p=**.” Note: correlations only measure the strength of a linear relationship (not u-shaped or other types of relationships). The scores for Pearson’s correlation are always between -1 (perfect negative linear relationship) and +1 (perfect positive linear relationship). The correlation value does not change if the independent (x) and dependent (y) variables are interchanged.If there is a significant linear correlation between two variables, then 1 of 5 situations can be true:There is a direct cause and effect relationshipThere is a reverse cause and effect relationshipThe relationship may be caused by a third variableThe relationship may be caused by complex interactions of several variablesThe relationship may be coincidenta
